PNEUMATIC RENOVATING-MAGHINE.

Toallwliomc'tnmyconccy'n: cit-1; zen of the United States, residin at New York city, in the county of New. ork and. State of New York, have invented new and useful Improvements in. Pneumatic Renodo more particularly with a novel arrangement of the parts of the -apparatus-and means for assembling certain of those parts upon a base-or thelikeu shown in m The object of this invention is to provide a' novel construction and arrangement of means for removably and replaceably. supporting the dust collector in cooperative relation-with the other necessary parts of a suction cleaning device. so that said collector may be readily removed for the purpose of emptying therefrom the'collected dust, thesaid dust collector "supporting means having-associated therewith suitable jaws for receiving and holding a propelling handle forthe apparatus.

This invention is illustrated and described in connection with apparatus of the type prior Letters Patent, Nos. 918,891, 918,896 and 918,897 dated April 20, 1909, as an'understanding of the object of the present invention willbest be obtained by this showing, but it is to be understood that the improvements of this invention may be associated'withany apparatus of other types-without departing from the spirit of theinvention.

In the accompanying-drawing disclosing the present embodiment of the invention, Figure 1 is aperspective view of a pneumatic renovating machine assembled by the device of this invention. Fig. 2 is a longitudinal sectional view taken vertically through the same. Fig. 3 is a detail view of thelower part of the apparatus showing the clamping plate, the handle being shown in section. Referring to the.draw1ng,'the reference numeral 1 designates a platform or base mounted upon wheels-9., the platform carrying the suction cleaning means 111 the present instance shown as a fan 3 driven by a motor Specificatlonof Letters Batent.

4 suitably conn'ected to the fan 3. The fan 3'is connected bya pipe 5 to the upper end of a dust collector 6 having in its lower end a vertical opening 7 disposed centrally therein. Carried upon the platform or base 1 is a plate .8 provided near one .end with an upstanding stud 9 fitting into said vertical opening? in the bottom ofthe dust c llector. The stud 9 is adapted to fit snug y in the opening 7 and-to thereby hold by friction, the dust collector in upright position upon the platform 1. It may be also noted that the dust collector'can be readily lifted from the stud 9 when it is desired to empty the collected dust from the collector. This plate 8, as may be best seen from Fig. 3,

extends across the top of the platform 1- near one end and is provided with a pair of clamping jaws 10 and 11 having concaved inner faces forming a cylindrical socket for the reception of the inner cnd of a handle 12. The jaws 10 and 11 are spaced apart slightly at their outer ends and are adapted to bedrawn together to bind upon the handle 12 by a bolt 13 with a nut 14 upon its threaded end which passes preferably up through the platform 1 and the jaws 10 and 11, the nut 14 being positioned against the upper side of the jaw 11. The bolt 13 thus not only clamps the jaws upon the handle 12, but also serves to secure one end of the plate 8 to the platform. A second bolt 15 is employed which passes up through the platform and through the plate 8 near its opposite end. Thehandle 12 may be of any approved. type and is shown in the present instance as havinga cross-bar 16 upon its upper end constituting hand-holds by means of which the operator maymove the machine from place to place. Connected to the fan 3 is any suitable means 17 for connecting the cleaning tool 18 to the fan.

It is of course understood that the structure above set fortlrmay be departed from to a considerable extent within the limit of the appended claim.

What I cliam is:

a handle for moving the base, a suction plate having an upstanding stud engaging In testimony whereof I have hereunto set the dust receptacle and a pair of clalnpmy hand in presence of two subscribing ing jaws engaging the handle, and fastening Witnesses.
